GRAT UPVC Ball Valve
In various stages of wastewater treatment, UPVC ball valves have become an ideal choice for ensuring stable and efficient operation due to their corrosion resistance, cost-effectiveness, and fluid control characteristics:
- Influent Stage: Rapidly responds to changes in water quality and quantity, precisely adjusts the opening degree, ensures stable influent flow, and effectively prevents corrosion of the valve body by corrosive media.
- Pretreatment Stage: Reasonably distributes flow to various units, adjusts flow velocity based on grid status, prevents clogging, ensures effectiveness, and significantly reduces maintenance costs.
- Biological Treatment Stage: Precisely controls aeration and chemical dosing flow based on IoT signals, optimizes dissolved oxygen and dosing amounts, and enhances treatment efficiency.
- Drainage Stage: With its sealing performance and smooth passage design, ensures stable discharge flow and pressure, integrates with monitoring equipment, and guarantees real-time compliance of drainage water quality.
The GRAT IoT mini ball valve is not only a precise breakthrough in fluid control technology but also a significant response to the era of smart water management. In today’s pursuit of green, low-carbon, and sustainable development, GRAT IoT mini ball valve provides solid support for promoting water resource recycling and improving environmental governance, making it an ideal choice for the wastewater treatment sector to face future challenges.With its stable and reliable operational performance and highly automated control capabilities, GRAT deeply integrates into the entire process chain of wastewater treatment, continuously empowering plants to achieve refined and intelligent operations.
